To @ZZ whont it 771/603/ concern.'

Be it known that we, LOUIS COTE and LOUIS E. COT, of St. Hyacinthe, in the Province of Quebec and Dominion of Canada,have jointly invented certain new and useful Improvements in Machines for Outlining and Grading Boot or Shoe Patterns, of which the following, taken in connection with the accompanying drawings, is a specification.

1o Our invention relates to machines for outlining and grading boot and shoe patterns and marking the same on paper or cutting the same from paper or other suitable material in which the principle of the pantograph is I5 employed and is animprovement upon the invention described'in the Letters Patent No. 469,775, issued to Louis Cote March 1, 1892; and it consists in certain novel features of construction, arrangement, and combination 2o of parts, which will be readily understood by reference to the description of the accompanying drawings and to the claims hereto appended and in which our invention is clearly pointed out.

z5 Figure 1 of the drawings is a plan of a machine embodying our invention with the marker orknife holder removed. Fig. l2 is a front elevation of the same. Fig. 3 is a partial section on line A A on Fig. 1 looking toward the left of said figure, but showing certain parts in elevation. Fig. Lisa partial plan of the same, drawn to an enlarged scale.

Fig. 5 is a sectional elevation' of the same parts, the cutting plane being on line B B on Fig. et. Fig. 6 is a vertical section through A the bed and vertically-movable frame cn line f C C on Fig. 1 looking toward the bottom of said gure. Fig. 7 is a partial sectional elevation, the cutting plane being on line D D 4o on Fig. 1 and looking toward the right of said igure. Fig. 8 is apartial sectional elevation, the cutting plane being on line E E on Fig. 1 and looking toward the right of said figure.

25 is a section on line I I on Fig. 23 looking toward the top of said figure. Fig. 26 is a sectional elevation illustrating the hinge con- 8o nection between the slide that supports the series -of tool-carrying bars and the bar of the pantograph7 and Fig 27 is a transverse section of the bars and illustrating the manner of supporting the former by the latter.

In the drawings, a is the bed or table upon which the cardboard or other material to be acted upon is to be supported and is secured in a fixed position to any suitable bench or frame of wood (not shown) and has mounted in 9o suitable bearings thereon the rocker-shafts Z7 Z), each provided with two arms or lifter-toes c c and each having secured to its rear end a toggle-arm d d, the movable ends of which arms are connected together by a com mon pin, from which depends a rod e, connected at its lower end to a treadle, (not shown,) by which said rocker-shafts may be partially rotated, one of said arms being slotted for the passage of said connecting-pin. A rectangular skeleroo ton frame f incloses said bed a and rests upon the lifter-toes c cin such a manner that it may be raised to a limited extent by the partial rotation of the rocker-shafts b b through the action of the togglearms d d when acted upon by said treadle.

The framefhas secured to its upper side, at its front corners only, the supplementary rectangular frame g, the under surface of which is raised a short distance above the upper su rface of the frame f, except at the two front corners, so thatthe sheet of material h to be acted upon may be easily placed in position upon the bedctbeneath said frame g, as shown.

The bars of the frame g have their inner edges grooved to receive the tenoned ends of the two bars fi t', which are freely adjustable therein and arranged to rest upon the material h to hold it in the desired fixed position, as shown in Figs. 1 and 6.

A radius arm orbar j is secured near one end to the hub 7c and is provided atits righthand end with the antifriction-roll Z, which rests upon the upper surface of the frame g, along which it rolls as said radius-arm is vibrated about the axis of said hub 7c.

The hub 7a is pivoted to the carriage m, provided with guide-wheels which rest in and are movable end wise of agroove formed in the upper surface ofthe bar n, arranged at a right angle to the front of said framef, said bar n being supported at its front end upon the rod o, which is movable endwise in a bearing in the stand p, and atits rear endby the trucks q, resting upon a plate forming an extension of the frame g, the rear end of said bar a being connected by the brace r to the outer end of the rod 0, as shown in Fig. 1. Another radius arm or bar s is pivoted to the hub 7c by the same pin which connects said hub to the carriage m and has 'fitted thereon, so as to be movable endwise thereof, the slide t, the central portion of which is slotted, as shown in Figs. 1 and 4. The slide 1, has pivoted thereto the slides it and Iv, provided with set-screws, by which they are clamped to the bars w and :0, respectively, as shown. rlhe slide t is provided with a hand clampingscrew, by which said slide may be clamped to the bar s at any desired point.

w is a bar fitted to and adjustable endwise in the slide u and connected at its front end by the pin 40 and the stand 36 39 to the slide a', fitted to and movable endwise upon the barj.

The construction, arrangement, and operation of the bars j, s, and w and the slide ,e are substantially the same as in the machine described in the before-cited Letters Patent, except as hereinafter specified.

A bar x is fitted to the slide fr, so as to be movable endwise therein, and rests at its front end upon the slide e, as shown in Figs. 4 and 5,

The bars w and c are connected together by the bars 1 and 2, in addition to the slidest and `u and o, in positions parallel to each other by pivot-pins 3, and the bars w and m have graduated scales marked upon their upper sides, as shown.

In the before-cited patent the bar extends toward the rear only to the point of connection to the bar 1; but in the present inventn tion it extends to the rear beyond said bar 1 to a greater distance than the bar w'.

Between the bars w and are arranged parallel thereto and to each other and equidistant from each other a series of bars 4, 5, 6, 7, 8, 9, 10, l1, 12,13, 14,15, 16,17, and 1S, each pi voted to tlie bars 1 and 2 and to one or more of the bars 19, 20, and 21, as shown in Fig. 4 and substantiallyasshown in said cited pat# ent, the front ends of said bars resting upon the slide .5', mounted and movable endwise of the bar j. Each of said bars 4` to 18 has formed therein, just at the rear of said bar y', a socket or perforation 22 to receive the knife or marker holding spindle 23, to the upperend of which is pivoted one end of the lever 24, fulcrumed on the stand 25, which is provided with the arm 26, having at its end the upwardly-projecting rib 27 to engage the slotted front end of the bar in which said spindle 23 is mounted. The lever 24 extends outward beyond its pivotal connection to said stand 25 and has pivoted thereto the latch-lever 2S, the outer arm of which is forced upward by the spring 29 to cause its inner end to engage the detent 30 when the outer arm of said lever 24 is depressed to raise the knife or marker from contact with the material being operated upon against the tension of the spring 31, substantially as in said prior patent and as shown in Figs. 14 and 15.

The bar w has secured thereto or formed in one piece therewith the arm 32, projecting upward and forward therefrom, upon which is firmly secured one end of the curved bar 33, the opposite end of which is similarly secured to the arm 34, extending upward and forward from the bar a; and secured to or formed in one piece therewith, as shown in Figs. 4 and 5. The curved bar 33 has secured thereto between its two ends the plate 35, which has formed therein a socket in axial line with the axis of the hole 22 through the bar 13, as shown in Fig. 4.

The right-hand end of the slide is provided with a stand 36, in which is mounted a truck 37 to rest upon the barj, and has firmly secured thereto the handle 38, by which the various bars forming the pantograph may be moved in any desired direction in a horizontal plane. The stand 36 is provided with ears or arms 39, by which and the pin 40 the bar w and the slide ,e are hinged together, as shown in Figs. 4, 5, and 26. The left-hand end of the slidezis also provided with a guidestand 41, in which is mounted an antifriction-truck 42 to rest upon the barj, as shown in Fig. 4. A cylindrical rod 43 is mounted in a fixed position in bearings in the gooseneck-like arm 44 at one end and in the curved stand 45 at its other end, with its axis par-4 allel to the front edge of the frames fand g and to the uppersurface of the bed d, and has mounted thereon, so as to be ad j ustable cnd- IOO IIO

Wise thereof, the sleeve-like hub 46, said rod and hub being provided with a spline-groove and a key to prevent said hub from being moved about the axis of said rod, as shown in Fig. 8. The sleeve 46 has formed upon opposite sides thereof the laterally-projecting hubs 47 and 48, in which are set the rods 49 and 50, respectively, at right angles to the rod 43, with their axes in the same horizontal plane as the axis of said rod 43, and said sleeve is provided with a set-screw 5l, by which it may be secured to said rod 43 in any desired position. The rod 49 has fitted thereon, so as to be movable endwise thereof, the circular disk 52, secured in any desired position thereon by the clamping-screws 53 and prevented from rotation on said rods by a suitable key fitting a spline-groove in said rod 49, as shown in Figs.24 and 25. The disk 52 has formed upon its under side the centrally-ar ranged circular hub 54, upon which is tted, so as to be revoluble thereon, the three-armed spider 55, which is secured in position thereon by the large-headed screw 56. The disk 52 has screwed into its upper surface the chambered hub 57, in which is mounted the locking-bolt 58, arranged to engage with one or the other of two holes 59, formed in said spider upon opposite sides of its axis of revolution, said bolt being pressed downward by the spring 60 and provided with a nut-like head 61, by which said bolt may be withdrawn from engagement with said spider when it is desired to reverse it.

Each arm of the spider 55 has formed in its under side a Tshaped groove 62, in which is fitted, so as to be adjustable lengthwise thereof, a nut 63, to which is fitted a clamping- Y screw 64, provided with a washer 65, between which and the head of said screw is clamped the pattern 66, as shown in Fig. 24.

The disk 52 has formed thereon or secured thereto the arm 67, having a hub at its outer end, in which is formed a bearing to receive the rod 68, to which said hub is secured in any desired position by the set-screw 69, as shown in Figs. 1, 8, 24, and 25.

The rod 50 has a hub 70 secured thereon in a normally-fixed but adjust-able position by the set-screw 7l, which hub is provided with an upwardly-projecting arm terminating in a hub 72, in which is formed a bearing to reeeive the rod 73, to which said hub is secured in any desired position by the set-screw 74.

The socket in plate 35 has fitted thereto, so as to be freely revoluble therein, the spindle 75, provided with an eccentric head 76, hav-v ing formed in its upper surface the lipped groove 77, extending transversely across it, in which is fitted the block 78, provided with the upwardly-projecting pin 79, upon which is mounted the grooved guide-truck 80, which bears against the edge of the pattern-plate 66, substantially as described in the before-cited prior patent. In said prior patent the bar corresponding to the bar j, in this application extended beyond the hub 7c toward the left of Fig. 1, was slotted longitudinally and had ad# justably secured in said slot a fulcrum-piri the lower end of which engaged a groove in a fixed plate beneath said bar, said groove being arranged parallel to the axis of the patternsupporting rod, and when said fulcrumpin was secured in the desired adjusted po'- sition in the slot in said bar the distance between the axis of said pin and the pin corresponding to the hub lo of the present invention always remained the same in whatever positions the bars of the pantograph might be placed in the operation of the machine until said fulcrum-pin wasadjusted to a new position in the slot in said bar. We have found that in the operation of the machine described in said prior patent when a pattern was to be cut or marked having two opposite edges of the same, but reversed, shape, so that the two halves of said pattern should be exact duplicates, one edge of the pattern (resulting from the operation of the machine) would be slightly shorter than the opposite edge. It has also been found desirable to cut or mark patterns varying in length in regular graded proportion, but of uniform width, which could not be accomplished by the machine described in said prior' patent. There arel some patterns used in the vmanufacture of boots and shoes that could not be graded and cut or marked upon the machine described in said prior patent because of the inability of the grooved guide-truck that controls the action of the cutting or marking tool to traverse the entire outline of the metal pattern on the machine, owing to passages or slits of considerablyless Width than the diameter of said truck. To obviat-e these several defects is the object of our present invention, and to this end we have modified the construction of the machine as follows: l

The barj, though extending to the left beyond the hub k, is not provided at its lefthand end with a slot and an adjustable pin set therein, and the slotted plate with which said pin engaged is omitted, said hub lo being pivoted to the reciprocating carriage m, as shown and described. The arm 44 has secured thereto or formed in one piece therewith the bar 81, arranged at right angles to the vertical plane in which lies the axis of the rod 43, and is provided in its under side with a longitudinal groove 82, in which is fitted, so as to be movable endwise therein, the rod 83, provided with a downwardly-projecting lug 84, in which is set a guide-rod 85, which projects laterally therefrom at right angles to said rod 83 and has mounted thereon, so as to be movable endwise thereof, a sleeve 140, provided with a socket to receive a ball formed upon one end of the bar 86, which is adjustably secured to the bars x and 87, respectively, by means of the swiveling sides 88 89 and 90 91, as shown in Figs. 1, 2, 3, 4, and 5.

The bar 87 is pivotally connected to the bar s at 92, as shown in Figs. 1 and 4. The bars 86 and 87 are graduated upon their upper AIOO IIO

IIS

surface to a scale corresponding to the scales upon the bars s, w, and and the bar 86 has an additional series of graduations designated by smaller Iigures. The rght-hand vertical face of the bar 81 is graduated to a scale of thirtieths of an inch in opposite directions from its center, and the lug 84 has secured thereon the index 93, as shown in Figs. 3 and 20. The rods 83 and 85 are clamped in the desired adjusted position by the handle 94, eccentrics 95, and clamping collars or vwashers 96, as shown in Figs. 1, 2, 7, and 20. Athreaded rod 96n is mounted in a fixed position in ears projecting from the bar 81 and has adjustably fitted thereon a pair of stop-nuts 97 and a pair of cheek-nuts 98, and lthe lug 84 has secured thereon the stand 99, which embraces the rod 96 between the pair of stop-nuts 97 and carrying at its upper end a truck 100, which rests upon a flat surface upon the bar S1, as shown in Figs. 7 and 20. The rod 43 has secured thereon in a fixed position the horizontal hub 101, which has formed in one piece therewith the vertical hub 102, in which is mounted the vertical spindle 103, provided with the large head 104 at its lower end, having set therein or formed in one piece therewith the radius-arm 105, the outerportion of which has a cross-section in the form of an inverted T, (see Fig. 27,) the upper end of said spindle having firmly secured thereto the disk 106, between which and the upper end of the hub 102 and between the lever end of said hub and the spindlehead 104 is inserted a series of balls 107, as shown in Fig. 3. The outer or right-hand end of the bar s has pivoted thereto the lower end of a swiveling hub 108, in the upper end of which is adjustably fitted the threaded shank 109, the upper end of which is forked and has mounted upon pins projecting inward from each prong of said fork trucks 110, which rest upon the projecting ribs of the radiusarm 105 and serve to support the outer end of the bar s and all the bars carried thereby at suitable heights above the upper surface of the bed a, as shown.

In some cases the pattern upon the machine from which other sizes are to be graded is of such a shape that it is necessary in order to mount it in the proper position upon the machine to employ two only of the clamping devices on the spider 55, as shown in Figs. 21 and 22.

In the cited prior patent the grooved guidetruck which engaged the edge of the metal pattern was mounted upon a pin set in a fixed eccentric position relative to the axis of the spindle about which the axis of said truck revolved as it was moved about the pattern on the machine.

In our present invention the pin 79, upon which the truck is mounted, is set in or formed integral with the block 78, as before described, and said block is provided with a threaded perforation to receive the adjustingscrew 11.1 provided with the collar 112, which is engaged by the forked arm 113, secured to one side of the eccentric head 76 of the spindle 75, as shown in Figs. 9, 10, 1'1, and 13, drawn to a greatly-enlarged scale. By this construction we are enabled when a pattern is to be cut or marked having slits orpassages too narrow to admit the passage of the truck 8O to remove said truck, adjust the block 78 and pin 79 until one side of said pin is inaxial line with the axes of the spindles 75 and 23, as shown in Fig. 12, apd cut the pattern by using said pin 79 to press against the metal pattern, said pin being made of steel and as small as is consistent with a due regard to strength.

The front end of the extension-plate 114 of the frame g has secured thereto the plate 115, having its rear upper surface graduated to a scale of thirtieths of an inch to facilitate the proper adjustment of the bar n in a direction parallel to the axis of the rod 43. The front end of the bar n has formed therein a slot which is engaged by a truck carried by the rear end of the short lever 116, pivoted to the plate 1.15 at 117 and having pivoted thereto between its two ends by a horizontal pivot the forked handle 118, provided with the adjustable slide 119, having in its under side a short pin 120, which engages one or the other of a series of grooves 121, formed in the upper surface of the plate 115, as shown in Figs. l, 2, and 3, and substantially as in the cited prior patent.

By the employment of the bars S6 and 87` and the freely-movable fulcrum of the bar 86 patterns of all sizes may be accurately graded from a single pattern on the machine, so that if the pattern used as a guide is symmetrical or has its two halves duplicates of each other the various sizes of patterns cut or marked by the machine will be properly graded and each half of each pattern will be an exact duplicate of its other half.

A plate 122 is secured in a fixed position on the hub 70, has formed in its upper surface a series of detent-grooves 123, and is provided with an ear 124, in which is formed a bearing for the rear end of the rod 68. A short lever 125 is pivoted at one end to said plate 122, and its other end engages the notched rear end of the rod 68 and has pivoted thereto by a horizontal pin, near the middle of its length, the hand-lever l26,constructed and arranged to operate in the same manner as the lever 118 for the purpose of reciprocating the rod 68 to readily adjust the pattern holding spider 55, as may be desired. The plate 122 is provided with two stop-screws 127 and 128 for limiting the movement of the lever 126, as shown in Figs. 1 and 8.

The right-hand end of the rod 43 has secured thereon a hub 129, formed upon or secured to the plate 130, which has formed therein a series of detent-grooves 131, is provided with the lug or ear 132, in which the rod 73 has a bearing, and has pivoted thereon the short lever 133, which engages byits mov- IOO able end the notched head of the rod 73, said lever having pivoted thereto between its two ends by a horizontal pivot the hand-lever 134, having an adjustable slide 135, provided with a detent to engage said grooves,substantial1y as in the case of the lever 118, said plate also being provided with the stop-screws 136 and 137, as shown.

The operation of our invention is as fol lows: The several parts of the machine being in the positions shown in the drawings, with the index 93 pointing to zero on the bar 81, and the pattern 66 is in the position indicated by the full outline thereof shown in Fig. 1, the frame f is raised by operating the togglearms d d to partially rotate the shafts b b, and the paper, cardboard, or other material to be operated upon is placed upon the bed beneath the bars i i. The arms d d are then returned to their normal positions by removing the foot from the treadle, when the bars z' i will rest upon said material and hold it in a fixed position, being pressed thereto by the Weight of the framef. The operator then seizes the handle 38 and moves the barj and the parts carried thereby about the axis of the hub la, so as to cause the guide-truck 8O to pass around the pattern 66 in the direction indicated by the arrow on Fig. 1, said truck being held in firm contact with said pattern throughout its entire perimeter. If a pattern is to be drawn or marked upon paper, the marker 138 is inserted in the tool-carrying spindle 23, as shown in Fig. 14; but if the pattern is to be cut from card or pasteboard the knife 139 (shown drawn to an enlarged scale in Figs. 16 and.17) is inserted in said spindle, as shown in Fig. 15, and said spindle isinserted in the proper spindle-carryingbar for the desired size of pattern, and said spindle is raised and locked in said raised position, as shownin Fig. 14. lVhen the truck 80 is broughtinto contact With the pattern 66, the lever 28 is disengagedv from the detent-notch 30, when said spindle 23 will be moved downward by the tension of the spring 29 until the point of the marker 138 or knife 139 comes in contact with the material to be acted upon, andthe operator moves the truck around the pattern 66, pressing said truck hard against said pattern, as described, and when said truck has reached the start-- ing-point a pattern will have been marked upon or cut from said material properly graded to the desired size, according to what socket-bar the spindle t' is placed in. It' said spindle is placed in the socket of bar 13, the pattern drawn or cut will be `an exact duplicate of the pattern on the machine; but if said spindle is placed in any other of the sockets 22 the pattern produced will be either larger or smaller than the pattern on the machine, according to whether said spindle is set in a socket in one of the bars 14 to 18 orin one of the bars 12 to 4, and as many sizes larger or smaller as the spindle is removed sockets from 13. In moving the truck 8O about the pattern, as above described, the bar j, though not connected directly thereto, practically vibrates about the axis of vibration of the bar 86, which is its point of connection to the sleeve 140, and the hub 7c and carriage m move along the bar n substantially as the pin d2 and the plate B2 moved along the slot c4in said cited prior patent under similar conditions; but as the sleeve 140 is at no time clamped to the rod 85, but is at all times freely movable endwise of said rod, controlled only by the movements of the bar 86, it follows that the movements of the marking tool or cutter when the spindle 23 is placed in any socket 22 other than the one formed in bar 13 are varied from the movements of the same tools under the conditions described in said prior patent, in which the bar corresponding to the bar j of this application was moved about a fulcrun1-pin firmly clamped to said bar, so that in all the movements of the pantograph said bar moved about a fulcrum-pin that remained at all times during suchoperation at the same dist-ance from the pivotal connection of the bars D and E of said patent and corresponding to the hub 7c of this application, while in ourpresent invention the distance between the pivotal connection of the barsj and s and the pivotal connection of the bar 86 to the sleeve 140, which is the center about which the pantograph is vibrated, varies to a greater or less extent, according to the adjustments of the slides connecting the bar 86 with the bars a; and 87 and the travel of the truck 80 lengthwise of the pattern. In said prior patent when the guiding-truck was moved in the direction of the length of the bar D-without vibrating said bar no movement of the pivot-pin d2 andthe plate B2 along the groove c4 took place and the distance between the vpins (Z2 and g remained constant; but in our present invention if the truck 80 is moved in the direction of the length of the bar Jwhen said bar is in the position shown in Fig. 1 and its right-hand end is held stationary the hub k and carriage m will be moved along the bar n toward the front or the rear, according to the distance the truck 8O is moved toward the right or left, respectively, while at the same time the distance between the axis of the hub lo and the pivotal connection between the bar 86 andthe sleeve 140 varies, as above set forth. It is by. virtue of this difference of construction and operation that we are able to accurately grade all sizes of patterns from a single pattern so that all of said graded patterns shall have the proper length upon each side of the central vertical line instead of being too short on one side of said line and too long on the other side, as hereinbefore described.

It should be understood that the centers of all the sockets 22, the axis of the hub 7e, and the center of the ball-and-socket joint connecting the bar 86 and the sleeve 140 are all in the same vertical plane at all times and that the slides t and u are adj usted upon the bars @a and w, respectively, to the graduation- IOO lIO

mark appropriate to the size of the pattern on the machine, which is determined by iirst measuring the whole length ot the boot or shoe pattern, including vamp and quarter, by a scale of sizes, and as the pattern upon the machine, as shown in the drawings, is a pattern ot' the quarter ot` a ladys boot, the length measure of which is thirty sizes, the slides t and u` are adjusted to the graduation-marks 30 on the bars .fr and uf, respectively, as shown.

The bar 86 and its adjustment upon the bars and S7 control the proportioning of the width of the produced pattern relative to its length, and therefore in order to properly adjust said bar 86, and thereby properly proportion the width of the produced patterns, the width of the model-pattern is tirst measured by a scale of widths ditfering from and independent of the scale of sizes, and the bar 86 must be adjusted upon the bar x according to said measure, and as the pattern on the machine, as shown in the drawings, measures forty widths the slide 88 should be adj usted to 40 on the bar the slide 90 to 10on bar S7, t-heslide 89 to 40 on barSG, and the slide 91 to a posit-ion on har 8G that will place the bar S7 parallel to bar It is obvious that when patterns of mens or childrens boots or shoes are to be graded, the appropriate pattern selected for use on themachine is first measured by a scale of sizes for its length and by a scale of widths, and the bars s and 8G are adjusted to the proper grad uations on thebars x, w, and S7, as above described.

Vhen it is desired lo mark or cut graded patterns havingtuller leg portions in proportion to their heights without increasing the proportion ot' the length ofthe foot, the operation is the same as described in said cited prior patent; so, also, the adjustment of the several slides to adapt the machine to dilterent sizes of guide-patterns on the machine or to change from cutting patterns according to the English and American scale of sizes to cutting patterns according to the French scale of sizes, substantially as described in said prior patent.

To cut or mark graded patterns which are required to be graded only in one directionthat is, in the direction of the height of the 'boot-but of uniform width in the direction of the length of the boot, as a stay or facing for the front of a boot, a model-pattern 141 of the desired shape is mounted upon the machine, as shown in Figs. 21 and 22. Then with the rods 83 and 84 adjusted, with the index 93 pointing to zero on the bar S1 and the marker or cutter raised, the operator moves the truck 80 into contact with said pattern 141 at 142, then drops the cutter into contact with the material, and moves the truck 8O from 142 to 143 in the direction indicated by the arrows on Fig. 21. Then the point 143 is reached, the operator moves the bar 85 toward the front a given distance-say threethirtieths of an inch-into contact with the front stop 97 and the bar u, carriage m, and the hub k toward the right by means oi.' the lever 118 a given distance-say eight-thirtieths ot' an inch. Then with the truck S0 resting against the edge of the pattern 141 the cut from 143 to 142 in the same direction is completed and the pattern produced Will be graded at its two ends, but will be o the same width as the pattern upon the machine.

When patterns are to be graded from a model-pattern on the machine having slits or passages in outline to be traced too narrow for the passage of the truck 80, said truck is removed from the pin 79 and the block 78 and pin 79 are adjusted until the periphery ot' the pin 79 is in line with the axis ot the spindle 75, when the cutting or marking of the pattern may be proceeded with as before by pressing the periphery of said pin 79 against the edge ot the pattern on the machine, the cutter shown in Figs. 18 and 19 being carried by the spindle 23.

The model-pattern (56 or 141 may be adjusted to a limited extent toward or from tho front of the machine by slackening the setscrew l53 and operating the hand-lever 126 so as to cause the detent on the slide 144 to engage the desired groove 123; but if a greater change in the position of the pattern is desired the two set-screws 53 and 6i) are slackened and the spider and its supporting-disk are moved by hand to the desired position, when said set screws are tightened to hold `said spider in a xed position. In like manner said pattern may be adjusted in the direction of the length of the rod 43 by the proper manipulations of the set-screws 51 and 74 and the hand-lever 134.

In outlining and grading some styles of patterns it is desirable to increase or diminish the height ot' the produced pattern to a greater extent than the length is increased ordiminished or to increase the height While the length is decreased, or vice versa. This may be accomplished in the following manner: It it is desired to produce patterns either larger or smaller than the pattern 66, (shown in Fig. 1,) but having a greater proportionate height than said pattern, the parts of the machine being in the positions shown in Fig. 1, the guide-truck 7G is moved around the pattern 66 in the direction indicated by the arrow on said figure until it reaches the upper right-hand corner of said pattern 66, when the set-screw 53 being slackened and the set-screw 69 being screwed down tight upon the rod 68 the handelever 126 is moved toward the front of the machine until it comes in contact with the stop-screw 128, thereby moving the pattern Gb' toward the rear of the machine a predetermined distance, when the detent on the slide 144 is engaged with a groove in the plate 122 to lock said pattern against movement in either direction. The movement ot' the truck is then continued in the same direction until it has passed around the left-hand rear corner ot said pat- IOL IIO

tern and arrived at a point at the same distance from the front of the machine as it was when the pattern was moved toward the rear. The hand-lever 126 is then moved toward the rear until it is arrested by the stop-screw 127, and the detent on the slide 144 is engaged with a groove in plate 122 to lock said pattern, when the movement of the truck is continued until the starting-point is reached, and the pattern being marked or cnt is completed, said produced pattern having a proper graded proportion either larger or smaller than the model-pattern on the machine, according to whether the marker or cuttter carrying spindle is set in one of the bars 14 to 18 or one of the bars 12 to 4, except that the leg of the produced pattern will have a greater proportionate height than the pattern on the machine. It a less proportionate heightis desired, it can be obtained by readjusting the stop-screws 127 and 12S and reversing the movements ofthe hand-lever when the modelpattern is to be adjusted.

In some cases it is desirable to produce graded patterns having a greater or less proportionate dimension in the direction of the length of the boot or shoe than the model-pattern, and Athis may be readily accomplished by slackening the set-screw 51, tightening the set-screw 74, moving the truck along the bottom of the pattern 66 until it reaches the righthand front corner of said pattern, and then moving the hand-lever 134 toward the right or left, according to Whether the proportionate length of the produced pattern is to be diminished orincreased, the stop-screw 136 and 137 being previously adjusted to the desired position to limit the movements ot' said lever, substantially as above described in reference to the hand-lever 126 and stops 127 and 128.
